There is a discrimination for players who play 25 min + 10 sec games. According to "e-time" concept as described in viewtopic.php?f=12&t=25, e-time for these games should be 31 min and 40 seconds which is HIGHER than 30 min game. Therefore 25 min + 10 sec game should be considered as 100 XP game. I hope this will be fixed soon in the next version of chesscube. Thank You!
